This is according to registered nurse Sheila Swift, who wrote an article published in the Knoxville News Sentinel about the risk of tots being poisoned by medications lying around the house.
She noted toddler proof packaging on prescription drugs can reduce adults' worry about the chance their youngsters will be able to access and ingest the pills, but described this as a "false sense of security".
Many children can work out how to open bottles despite the designs used to keep them from doing so, the expert stated.
"Place all medications behind a safety lock accessible only by an adult," she recommended.
Dr Randall Bond, medical director of the Drug and Poison Information Center at Cincinnati Children's Hospital Medical Center, recently warned the problem of infants being poisoned by medication is getting worse, not better.
